The effect of temperature on gonad, embryonic development and survival rate of juvenile seahorses, Hippocampus kuda Bleeker

Physiological and behavioral responses of temperate seahorses (Hippocampus guttulatus) to environmental warming

“…All these studies point that temperature may affect survival, growth, feeding, behavior, reproduction and even skin color of seahorses (Wong and Benzie 2003;Foster and Vincent 2004;Lin et al 2006Lin et al , 2009Sheng et al 2006;Koldewey and Martin-Smith 2010 Due to their attractive appearance and peculiar ecology facts, like male pregnancy and monogamy, seahorses are considered flagship species for conservation campaigns , which makes them ideal species to draw attention to climate change issues. With the present study, we attempt to investigate the effects of increasing water temperature on the metabolic rates, feeding rates and behavior patterns of the temperate seahorse Hippocampus guttulatus.…”

Effects of light intensity, stocking density, feeding frequency and salinity on the growth of sub-adult seahorses Hippocampus erectus Perry, 1810

“…Seahorses are frequently taken as trawl bycatch and are vulnerable to destruction and degradation of their habitats (Vincent, 1996;Martin-Smith and Vincent, 2005), leading to sharp declines in wild stocks of seahorses in recent years. The artificial rearing of seahorses, sometimes on a commercial scale (Forteath, 1996;Lin et al, 2006), has partially alleviated the pressure on wild stocks (Lu et al, 2001;Sheng et al, 2006). However, the low survivorship of juvenile seahorses and low reproductive efficiency of the broodstock seahorses have restricted seahorse culture for many years (Herald and Rakowicz, 1951;Scarratt, 1995;Wilson and Vincent, 1998;Wong and Benzie, 2003;Lin et al, 2006).…”

The effects of illumination, feed ration, stocking density and gender segregation on growth and survival have been examined in Hippocampus abdominalis (Woods, 2000(Woods, , 2003a(Woods, , 2005.…”

Effect of temperature on yolk sac utilisation and growth of newly hatched larvae of cobia Rachycentron canadum (Linnaeus, 1766)

“…In Pagellus erythrinus, within the temperature range of 18-21°C, higher efficiency of yolk utilisation was noted at 18°C and the total length of yolk-sac larval stage decreased with rise in temperature (Klimogianni et al, 2004). Slower embryo development was reported at lower temperatures by Small and Bates (2001) and Lin et al (2006), while higher temperature resulted in faster embryo development (Das et al, 2006). However, sub-optimal conditions can increase the occurrence of fatal deformities and mortalities (Laurence and Rogers, 1976;Linden et al, 1979;Das et al, 2006).…”
